A child who weighs 55 pounds receives a prescription for cefotaxime 150 mg/kg/day intravenously in divided doses every 6 hours.
How many mg should the nurse administer each day?
3000 mg.
3300 mg.
3600 mg.
3750 mg.
The Correct Answer is D
Step 1 is to convert the child’s weight from pounds to kilograms since the dosage is prescribed in mg/kg. We know that 1 kg is approximately 2.2 lbs. So, the child’s weight in kg is 55 lbs ÷ 2.2 = 25 kg (rounded to the nearest whole number for simplicity).
Step 2 is to calculate the total daily dosage. The prescription is for 150 mg/kg/day. So, the total daily dosage is 150 mg/kg/day × 25 kg = 3750 mg/day.
So, the correct answer is, after analysing all choices, the nurse should administer 3750 mg of cefotaxime each day.

Correct Answer is C
Explanation
Choice A rationale: While monitoring temperature is important for a client with meningitis to track the resolution of infection, it is not a prerequisite for administering penicillin. It does not prevent life-threatening complications.
Choice B rationale: Assessing the level of consciousness is a critical part of the neurological assessment for meningitis. However, it is not the specific priority action required before administering a first dose of an antibiotic.
Choice C rationale: Penicillin carries a high risk of anaphylaxis. The nurse must verify the client's allergy history to ensure safety, as a previous reaction to penicillin or cephalosporins could lead to a fatal allergic response.
Choice D rationale: While cultures must be obtained before starting antibiotics, this question specifies the provider has already ordered the medication for an identified organism (Streptococcus pneumoniae), implying the diagnostic cultures have already been completed.
Correct Answer is ["30"]
Explanation
The correct answer is 30 mL/hour.
Step 1 is to calculate the total amount of norepinephrine in the IV bag: 4 mg norepinephrine ÷ 1000 mL = 0.004 mg/mL
Step 2 is to convert the patient's weight from pounds to kilograms: 176 pounds ÷ 2.2 = 80 kilograms
Step 3 is to calculate the total amount of norepinephrine the patient will receive per minute: 2 mcg/min × 60 min = 120 mcg/min
Step 4 is to convert micrograms (mcg) to milligrams (mg): 120 mcg ÷ 1000 = 0.12 mg
Step 5 is to calculate the total volume of norepinephrine needed per hour: 0.12 mg ÷ 0.004 mg/mL = 30 mL/hour
Therefore, the nurse should program the infusion pump to deliver 30 mL/hour.
